With redirect.rd_fragment now implemented, it should be possible to list redirects where the target contains a broken section anchor. For example, if the redirect page "Baz" contains "#REDIRECT [[Foo#Bar]]" and the "Bar" section no longer exists on the page "Foo", "Baz" would be listed somewhere in the user interface. This could be implemented in a separate special page or in Special:BrokenRedirects.
There's still no guarantee that the target anchor of the redirect is pointing to a section as opposed to a hand made <div id="blah"> thing. However, ignoring that we also don't store what sections actually exist on a page (as far as I'm aware) in the db. So there's still a fair bit more to do before that can happen.
